To all ac/mm it may come m:

Be it known that I, JosnrHGmss a Gillizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Impr rcmcnts in Building Con.- structions, of w iich the following is a speci fication.

This invention relates to building construction and one of the principal objects of the invention is to provide means whereby a substantially monolithic structure may be obtained without the use of removable molds.

Another object of the invention is to provide an improved building block and meaiis for interlocking separate walls constructed of said blocks.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this application, and in which Figure 1 is a perspective view of one of the blocks. Fig. 2 is a vertical longitudinal sectional view through one of the walls. Fig. 3 is a transverse sectional view on the line 33 of Fig. 2. Fig. 4: is a sectional View showing the connection of an additional wall to provide an air space. Fig. 5 is a detail perspective view showing the corner construction of a building constructed of said blocks. Fig. 6 is a horizontal section taken on the line 66 of Fig. 5.

Referrino" more particularly to the draw-. ing the wall shown in Figs. '2 and 3 is constructcd of? a plurality of blocks 1 each similarly constructed and having agroove 2 in its upper edge and similar groove 3 in one end. The lower edge of the bloclr has projecting therefrom a tongue 4. adapted to engage the groove 2 of blocks below thesame 'in the wall and is also provided with a tongue 5 at the opposite end of the block adapted to engage in the groove 3 of the block adjoining the same to the left. The groove 3 forms a right angular continuation of the groove 2 while the rib or tongue 5 forms a right angular continuation of the rib or tongue The groove has a longihas and composits end t e The base with sockets l0 Cf verse channels It? of the block to one side of the groove 2 and "adjacent the socketsare other sockets 12 all for a purpose to be hereinafter described.

In order to lock the blocks together to form a vertical wall there is provided U shaped connectors 13 which lie in the grooves- .6 and'S' and have their depending cnds or i legs seated in the recesses 7 and 9. To fur the-f insure rigidity of structure pins 14 are seated in the sockets l2 and in similar sockets-15 formed in the tongue it. These parts effectually prevent any relative longitudinal movement between the blocks and as the blocks are lap-jdinted as shown in Fig. 2-,.

the superimposed blocks hold the connectors 13 in place. In order to jointwo similarly constructed walls together as shown in'Figs.

3 and aU-sha'pcd connectors lti are provided whose bodies he in the channels 11 and whose legs lie in the-sockets 10. These connectors effectually hold the walls in separated relation and tie them" together so that when filled as shown at 17 the two walls and the intermediate filling form a substantial monolith for the cement filling 17 prevents movement of the U-shaped connectors 16 and also ties the superimposed blocks 1 together as will be readily understood. In this manner a substantially monolithic building may be produced of cement without usin the removable forms now commonly employed for this purpose.

In Fig. 4 an additional wall 18 is shown.

connected to the other wall and with the filling so as to leave an air space 19'Whl0ll is uninterrupted save for the connectors 16.

Figs. 5 and 6 only illustratehow the blocks are -connected together at the corner-of the building. One of the corner blocks as shown at ZO'being phovided with a groove 21 in one side to receive the tongue 5 of the adjoin- .ing right angular block, the next tier of the blocks is lap-jointed with the lower tier so as to interlock the tiers together.

What is claimed is .1. In a building construction, a pair of walls comprising separate su erimposed tiers t tongue and grooved lJHilC ing blocks having sockets-"therein, U-shapcd connectors seated in the sockets and held in position by l the tongues of superimposed blocks and binding filling arranged between the separate walls and surrounding the connectors.

In a building construction, a pair of s Allied walls, each constructed oi superiinposcdtiers of tongue and grooved buildllO
